`to claims. (c1. s- 364) The following is a full, clear and exact description, such as will enable others skilled in the art to.whichrit appertains to makel and to use the same, reference being had to the accompanying drawings which illustrate the preferred form of the invention; though it is to be understood that the invention is not limited to the exact Vdetails of construction shown and described, as it is i obvious that various modifications thereof within 10 the scope of the claims will occur to persons skilled in the art; I

In said drawings: Fig. l is a partial side elevation of al mine car constructed in accordance with this invention, parts being broken away along the line I--I o Fig. 2 toshow other parts more clearly;

Fig. 2 is a partial top plan view of the mine car shown in Fig. 1; and 1 Fig. 3 is a vertical transversesection of the mine car shown in Fig. l taken on the line 3 3 of Fig. 2. f

It is an object of this invention to provide a mine car 'of improved construction in which the journal boxes directly support the side-floor portions. It is also an object of this invention to provide a `construction in which the sills and center floor portion are connected so as to prevent distortion of the car body by the load on the center iioor portion. Y i

With these and other objects in View amine car constructed in accordance with this invention comprises, as shown in the drawings, flanged sills I formed of Z-shape pressings `or rolled shapes and arranged with outwardly projecting top flanges 2 and inwardly projecting bottom flanges 3, the bottom flanges 3 of the sills I being joined by tie `plates' 4 `,riveted thereto. The

tie plates 4 are connected to the outwardly projecting flanges 6 of the inverted U or `trough shaped draw and buffer beam 1 which extends centrally of the car from end to end. Longitudinally extending planks 8, gained along `an edge to fit the flanges'of the sills I `and buffer beam 1 are secured to the tie plates 4 bybolts 9 and with the web IIJ of the buffer beam 1 form the center portion of the floor of the car.

The webs II of the sills I are Vprovidedwith ,Vjtheside iloor portions I1` extending horizontally from the top flanges 2 and formed of plates having their outer portions bent upwardly to form the car sides I8 integral with the side floor portions I1. The side floor portions I1 are provided with openings portions ofthe wheels 20 mounted on the axles I2 project-and pressed wheel hoods 2| secured to the side floor portions I1 by` rivets 22 extend over the tops of the wheels 20 and close the openings |9.` The side floor portions I1 are secured to the upper surfaces of the top flanges 2 of the sills I and rest upon the outer portions 23 of the journal boxes |3'which project above the flanges I6 of the journal boxes I3 and are provided with recesses to receive the heads of the rivets 22 which secure the wheel hoods 2| to the side iloor portions I1. The side walls I8 have their opposite ends connected to end walls I3', the side and end Walls being stationary and each thereof contributing to the support of the other. p

Extending between the sills I at the axles I2 are Aaxle housings 24 of substantially inverted U-shape with laterally projecting horizontal flanges 25 and increasing inheight and decreasing in width at the ends ,where they extend to the tops of the sills I and are provided with out- 'wardly extending horizontal flanges 26 which overlap the inner edges of the side floor portions and thetop flanges 2 of the sills I and are se- 'cured thereto by the rivets 21, the rivets 21 hav- 'edby a tie 3B shown'` as a flanged plate havinga horizontal flange 3| resting on the planks 8 and a vertical flange 32 havingmat its endszlaterally projecting vertical flanges 33 secured `to the Webs II of the sills 2 by rivets 34. Angle brackets 35 riveted to the vertical flange 32 of the tie 3U and the webs II of the sills aid in securing the tie 30 to the sills I.

The horizontal flange 3| of the tie 30 is secured to the center portion of the floor by the bolts"35 .1 which engage the horizontal flange 3 I, the planks 3 and a strap brace 31 which passes beneath Athe center portion of the floor and extends `to each Iside of the car.' The brace 31 is fastened to the bottom flange 3'of the sills Aby the rivets 38 and I I9 intowhich the upper'` outside of the sills is bent upwardly to contact with the lower' surfaces of the outer portions of the plates forming the side portions II of the floor and with the outer surfaces of the car sides and is fastened thereto by rivets 39. Additional braces 40 of similar construction and secured to the floor and sills I in the manner just described are placed at the ends of the car and between the ends of the car and the axle housings 24. The braces 40, sometimes called binders or ties, are connected to the central floor planks, the side floor portions Il and to the side walls I8 of the car body by a suitable bolt or rivet connection as may be desired.

It will be noted that in a car constructed as above described the planks forming the center portion of the floor may be readily removed for replacement or repair by removing the bolts securing the planks in position and sliding' the planks toward an end of the car and that, when in position,` the floor planks are given adequate support by the tie plates 4, braces 31 and 40, flanges 3 of the sills I,flanges 6 of the buffer beam 1 and the bolts which secure the planks to the flanges 25 and 3| of the axle housings 24 and tie 3U, respectively. It will also be noted that the journal boxes I3 and axles I2 may be removed by removing the bolts I5 and that, when in position, .the journal boxes I3 directly support the side portions I'I of the floor and it will be further noted that the axle housings 24 and tie 30 brace the car body at the center and prevent deformation of the car body by reason of the load upon the center portion of the floor. Manifestly the bolts 9 and 36 are readily removable and when so removed the planks il of the floor may be removed longitudinally of the car from beneath the axle housings and the braces extending transversely of lthe car above said planks, thus facilitating repairs.

'I'he buffer beam 'I is preferably formed of metal as showin in the drawings, Fig. 3, and is so posi- `tioned as to resist a great portion of the builing shocks to which cars of this type are commonly subjected. The end portions of the buffer beam andtheplanks forming the floor are broken away -as the portions not shown are of conventional type.

The planks 8 forming parts of the central floor portion extend longitudinally of the car Vand parallel with the side sills I, so that the grain of the wood extends longitudinally of the ca-r body.
